Abstract

This study aimed to examine performance changes in lacrosse
players during a 24-week competitive season (including 22 weeks
of periodized resistance training (RT)). Eleven male lacrosse
players (age 24.5 ± 4.3 years, height 180.4 ± 5.6 cm, body mass
80.5 ± 5.7 kg, 1 repetition maximum (1RM) back squat (BS) 113.3 ±
17.8 kg, 1RM power clean (PC) 67.2 ± 19.7 kg) participated in this
study. Testing included 5-, 10-, 20-m sprints, change of direction
(COD), countermovement jump (CMJ), and squat jump (SJ).
Testing sessions occurred during week one (T-1), week six (T-2),
week 15 (T-3), and week 24 (T-4) of a domestic season. Significant
improvements in 20-m sprint performance occurred from T-1 to
T-4 (3.04 ± 0.07 seconds, 2.98 ± 0.08 seconds, p = 0.018). Left
leg COD tests significantly improved from T-1 to T-2 (3.20 ± 0.15
seconds, 3.10 ± 0.13 seconds, p = 0.005), and T-1 to T-4 (3.20 ±
0.15 seconds, 3.07 ± 0.12 seconds, p = 0.014). Right leg COD tests
significantly improved from T-1 to T-4 (3.20 ± 0.15 seconds, 3.08
± 0.12 seconds, p = 0.002), and T-3 to T-4 (3.20 ± 0.15 seconds,
3.08 ± 0.12 seconds, p = 0.001). SJ height significantly decrease
from T-1 to T-2 (38.2 ± 2.63 centimeters, 36.7 ± 2.57 centimeters,
p = 0.008). Results demonstrate that improvements in sprint and
COD performance can occur during the season in male lacrosse
players engaged in periodized RT, therefore coaches and strength
and conditioning coaches should focus on development rather than
maintenance in season.
